Maintain ideal spa water balance easily with SpaGuard® Rapid-Dissolve pH Decreaser Tabs (1.25 lb). These convenient effervescent tablets dissolve quickly to lower high pH and restore optimal water balance. Proper pH prevents cloudy water, protects spa surfaces, and ensures comfortable, irritation-free soaking. Designed specifically for the smaller volumes and higher temperatures of spas and swim-spas, each tablet precisely lowers pH by 0.1–0.2 units for accurate adjustments. Simply drop the required number of tablets into the spa water with the circulation system running—no mixing, pre-dissolving, or measuring powders required. Compatible with all sanitizer types including chlorine, bromine, ozone, and saltwater systems, this product helps reduce scale buildup and extend the life of your spa components. With fast results and simple dosing, SpaGuard® Rapid-Dissolve pH Decreaser Tabs make routine water care quick, clean, and reliable.
